Deye SE-F12 Max Low Voltage Storage Battery 11.8 kWh LiFePO4 Heated
The Deye SE-F12 Max in its heated version is a low voltage storage battery of 11.8 kWh with lithium iron phosphate (LiFePO4) cells, 230 Ah of nominal capacity and 51.2 V. It is designed for residential PV systems and small commercial installations: it stores the energy produced during the day and returns it in the evening or during grid outages, increasing the share of self-consumption.
The IP65 / NEMA 3R enclosure and the intelligent thermal management with optional heating allow installation outdoors, in a garage or in unconditioned rooms: when charging, the battery works from 0 to 55 °C, which becomes -20 to 55 °C with the heating function. It is wall or floor mounted, communication runs over CAN 2.0, RS485 and Bluetooth, and it is compatible with Deye low voltage hybrid inverters and with the Deye Cloud platform. Up to 32 units can be connected in parallel (64 with a CAN-Box).
